Abstract: A data recording apparatus includes two magnetic recording heads which are spaced apart along the length of an exchangeable magnetic recording tape. A switch normally connects an input data device to the first recording head such that data is recorded in a normal fashion. When it has become necessary to exchange a new tape for an old one, the incoming data is switched to a store where it is held as the tapes are exchanged. When a new tape is ready to record data, the switch is returned to its normal position such that data in the store is recorded by the second recording head concurrently with incoming data being recorded by the first recording head. The heads are spaced apart by a distance such that stored data recorded by the second recording head does not overlap incoming data recorded by the first head.
